BINDER.

' Ap plicati on filed August 1,0,119'2'2. Serial No. 5805916.

To all whom it mag concern: g

Be it known that I, BERNARD M. KRELL, a citizen of the United States, residin in New York, N. Y., in the county of ew York and State of New York, have invented certain new and useful Improvements in Binders of whichv the following is a specification;

This invention relates to binders for sewing machines or devices for applying edging or collarettes to the edge of fabrics thoug it is noted that the invention is in some respects not limited to binders nor even to sewing devices. 4

One Object of the invention is to provide .a device of this kind in which the upper and lower elements of the binder receive the upper and lower layers of the edging and are separable for the easy insertion of the body fabric. Another object of the invention is to provide an apparatus or device of this kind in which said upper element is attached to the presser foot of the sewing machine for automatically separating said elements as the foot is raised. V Another object of the invention is to provide in an apparatus or device of this kin'd efficient guide means for guiding the edging to the binder. I

Other objects of the invention are to improve generally the simplicity and efliciency of such devices and to provide a device or apparatus of this kind which is durable, economical to manufacture and operate and which will not get out of order.

The inventive features for the'accomplishment of these and other obj ectsare embodied in an improved binder which, briefly stated, comprises in combination with the presser toot, an upper binder element secured to'the' foot, a fixed lower binder'element under the upper element superposed opposed guide channels for discharging into said channel elements andcurvingjrearwardly and laterally toward the receivingend, and a forwardly opening channel shaped yoke portion joining said guide channels at the receiving end and terminating short of the curved portion.

.7 Other objects of the invention will appear as the description proceeds; and while herein details of the invention are described, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed.

In the accompanying. drawing, showing by wa of exampleyone of many'i'possible embodiments of the invention Fig. 1 is a plan of the binder andassociated presser oot;

Fig. 2 is a side elevation of'the' binder and foot; U V.

Figs. '3, 4 and 6 are vertical sectional views respectively taken on the lines 15-13,

and 5-.5 of Fig. 1, looking in the direction of the arrows .of said lines; and

Fig. 6 is a fragmented perspective view of the body fabric and edging.

My improved binder is intended itor'use with sewing machines for attaching. to

body fabrics lO, (.Fig. .6) collarettes or edging comprisingupper and lowerlayers '12 and 13 secured together by overseaming at the outer edge 14 and having inwardly turned creased inner edges 15 and 16. The binder itself is used in combination with'th'e presser foot 17 1) of a sewing machine (not shown) and is in part. carriedby .a bracket plate .18 for attachmentto "the bed of the machine and provided with anmupstanding flange forming an end guide face lower 'member 22 downwardly inclined toward its edge with an inclination very flat at the rear end and gradually steeper at the 'front end. The wide .upper member 24 forms a partof or issecured'tothe forward part of the lower face o fthe inside part of the: foot 17 and is movable. up and down therewith to permit theinsertion of'the body fabric 1-) between said creased edges 15 and 16 and has its edge portion downwardly inclined and disposed close to said face 19 and is provided with a rearwardly extended reduced portion between said face and the foot. The receiving end of the edge 21 is slit and the forward ends 26 of the members diverged to aid in the insertion of the upper layer.

A channel shaped sheet-metal lower binder element 30 (Fig. 3) closed at the outer side 31 and receiving the inner edge of said lower layer is disposed under the upper element 20 approximately symmetrical therewith relative to the plane of the body fabric 10 and is formed with a narrowupwardly and inwardly inclined upper member 32 of forwardly increasing inclination, between which, and said narrow lower element 22 of the upper member the body fabric is secured. The lower element also comprises a wide inwardly and upwardly inclined lower member 35 secured to said guide face 19.

Integral with said lower element 30 is a guide 36 1) extending rearwardly from said elements and provided with a rearwardly and laterally curved portion 37 (Figs; 1 and 4) merging into a substantially straight receiving portion 38. Said guide 36 is formed with lower and upper guide channels and 41 for guiding said layers into said upper and lower elements respectively, said channels being approximately vertical and opposed to each other at the curved portion 37 (Fig. 4) to permit the easy curving of the layers 12 and 13 and gradually approaching horizontal and becoming frontwardly opening at the receiving end portion 38 (Figs. 1 and 5) to permit the easy insertion of the layers, as the layers 12 and 13 are more easily insertible if nearly parallel to each other. Said channels 40 and 41 are connected at the receiving end portion 38 by a rearwardly closed channel shaped yoke portion 43 receiving the outer edge 14 of the edging and being cut away,

as at 44 at the curving portion 37 to permit puckering of the edging thus to prevent the choking of channel shaped yoke portion. A body fabric supporting plate 45 secured vto the top face of said upper member 32 of the lower binder element 30 extends laterally away from the binder elements for supporting the main body fabric 10.

The operation of the device is simple and obvious. The binder is attached relative to the foot, as shown; the edging started in as shown by the dotted lines in Fig. 1,

with the inner edges 15 and 16 in the channels 40 and 41 and the overseamed edge 14 in the channel yoke 43. The edging is then pushed. in until the layers 12 and 13 dispose themselves in thebinder elements 20 and 31,

-as indicated in Fig. 3. The foot 17 is then raised to permit the easy insertion of the body fabric 10 between the layers 12 and 13, after which the .foot is lowered and the stitching operation commenced.
